At the end of Bistri grabn, the Krofln homestead with two buildings, a house with a former mill and an outbuilding, is pressed on a narrow ledge between the stream and the almost overhanging wall of the steep hill called Kozjek. It was once home to a milliner, plumber – called “špengler”, a carpenter, and a worker in a nearby industrial plant. By the first half of the 19th century, there was also a sawmill. The homestead was renovated between 1998 and 2000. In the former residential part, there is now a permanent museum collection on display.
